Patent CA-2379440-A1 (CA)
Title: Osmotic distillation process
Inventor: BOWSER JOHN J
IPC: B01D61/36
Filed: 2000-07-28
Abstract: A method of raising the concentration of a liquid mixture utilizing osmotic distillation to transfer a volatile component from the mixture in contact with one side of a nonporous, preferably high free volume, gas permeable membrane (32) to a strip solution in contact with the other side of the membrane. Due to its nonporous nature the gas permeable membrane resists penetration and wetting by oily components that may be present in the feed mixture. Similarly, occlusion of the membrane by solids is resisted. Preferably, an amorphous copolymer of perfluoro-2,2-dimethyl-1,3-dioxole is useful for the gas permeable membrane. Osmotic distillation utilizing such high free volume, nonporous gas permeable membrane can concentrate difficult liquid mixtures such as pulpy fruit juices, and especially, limonene-containing juices, for example, orange juice. The process can be operated at high flux for long durations between membrane cleanings. Additionally, less contamination of the strip solution in a tank (22) into the feed mixture in the tank (40) occurs to provide a high quality concentrate.

Title: Process to remove ferric iron impurities from an acidic aqueous solution used in the electro-winning of copper
Inventor: MILBOURNE JOSEPH CHARLES
IPC: C22B15/00
Filed: 2002-04-17
Abstract: A process for the removal of primarily iron impurities from acidic aqueous electrolytic solutions used in the electro-winning of copper is described. Strong base Type 1 ion exchange resin is used to remove acid from the solution resulting in a treated solution that contains only a small amount the original acid but all of the dissolved salts. This low acid treated solution is then processed using standard processes such as adjustment of the pH or oxidation potential to remove the iron impurities and the solution containing valuable process cobalt is returned to the electrolyte solution to continue the extraction of copper.

Title: Vapor-liquid contact apparatus
Inventor: NUTTER DALE E
IPC: B01F3/04
Filed: 2000-10-02
Abstract: Vapor-liquid contact apparatus for chemical processing in-cludes a vessel containing a plurality of spaced horizontal trays which sup-port a vapor-liquid mixture, and downcomers which carry liquid down from one tray to another. Each tray has an infeed area, a bubbling area which has apertures for introducing vapor into the vapor-liquid mixture on the tray, and a liquid exit opening at the downstream end of the bubbling area. The downcomer receives the vapor-liquid mixture from the bubbling area, and it has a floor which increases the residence time of the vapor-liquid mixture in the downcomer. The floor forms an outlet which feeds liquid to the in-feed area of a subsequent tray. The downcomer outlet is an elongated slot formed between a convex outer edge of the floor and a convex outer edge of the downcomer cross section. To provide more uniform flow across the width of a bubbling area, the outlet slot which feeds the bubbling area is not wider, and is preferably narrower, at its centerline than at locations which are laterally spaced from the centerline.

De tels promoteurs peuvent être utilisés avec une multitude de gènes tels que le ipt, le CKI1, ou le (knotted1), de manière à induire la formation de ramifications en présence d'un inducteur approprié. Les promoteurs peuvent être utilisés avec des gènes induisant des embryons somatiques tels que leLec1 ou le SERK afin d'élaborer des embryons somatiques pouvant pousser dans des semis puis dans des plantes. Le promoteur peut également être utilisé avec des gènes de résistance aux antibiotiques ou aux herbicides, qui peuvent être ensuite régulés par la présence ou par l'absence d'un inducteur, plutôt que d'être des gènes constitutifs.

Patent CA-2391185-A1 (CA)
Inventor: GOZDZ ANTONI S
IPC: H01M50/426
Filed: 2000-10-19
Abstract: A separator (16) for use in laminated multi-layer electrochemical cell device structures. The separator comprises a microporous polyolefin membrane (24) with a polymer coating layer (26). The separator is treated to provide a deposited coating of a primary plasticizer (28) for the polymer coating layer. The device positive and negative electrodes comprising a polymeric matrix composition (12, 18) and separator are assembled and laminated at a compressive force and temperature at which the plasticizer film softens the polymer coating of the separator sufficiently to establish a strong interfacial bond with the matrix polymers of the electrodes and thereby form a laminated unitary cell structure. The plasticizer subsequently volatilizes from the structure to further strengthen the interfacial bond, yet its temporary presence in the interfacial region of the multi-layer cell structure enables lamination of the cell members at a temperature below the pore-collapse temperature of the separator membrane.

Title: Pressure sensitive mat with breathing tube apparatus
Inventor: SMITH TOBY E
IPC: A61B5/11
Filed: 2001-02-23
Abstract: This invention relates generally to patient monitoring systems and more particularly concerns devices and systems used to monitor bed patients in hospital or other care-giving environments. In accordance with a first aspect of the instant invention, there is provided a pressure sensitive mat which has been completely sealed around its exterior edges. The interior of the mat is kept in communication with the atmosphere by way of a section of flexible tubing which encloses the attached electrical line. One end of the tubing is sealed inside of the mat and the other end is open to the atmosphere, thereby providing a passageway for air to reach the interior of the mat. This arrangement, however, protects the interior of the mat from exposure to fluids near the perimeter of the mat and allows the mat-portion of the invention to be completely submersed without adverse effect, if that should become necessary.

Abstract: Procédé et appareil pour différencier les échos ultrasoniques réfléchis depuis divers objets dans un réservoir contenant un liquide. Des signaux ultrasoniques sont générés dans un transducteur ultrasonique à destination d'un liquide contenu dans le réservoir. Les échos ultrasoniques sont reçus par le transducteur depuis divers objets dans le réservoir, y compris une surface du liquide, en réponse aux signaux ultrasoniques générés; ils sont transformés en signaux d'écho électrique représentatifs. Des échantillons de données relatifs aux signaux d'écho électrique sont générés et traités par un processeur de signaux en utilisant un traitement de fonction d'ondelettes destiné à générer des coefficients d'ondelettes correspondants dans un domaine d'ondelettes. Les coefficients d'ondelettes des échantillons de données sont utilisés pour distinguer les échos ultrasoniques réfléchis depuis les divers objets dans tout le réservoir ou une partie de celui-ci. Dans un mode de réalisation les échos réfléchis depuis la surface du liquide sont distingués des échos réfléchis depuis les autres objets sur la base des coefficients d'ondelettes des échantillons de données d'écho dans chacun des cas. Dans un autre mode de réalisation, l'énergie de chacun des échos ultrasoniques déterminés à partir des coefficients d'ondelettes correspondants est utilisée pour distinguer les échos ultrasoniques provenant des diverses surfaces réfléchissantes.
